Abstract

The present invention relates to medial plantar plates for use in medial column arthrodesis. An article comprising a unitary plate configured to conform to a patient's foot. The plate has a dorsal portion shaped to conform to the dorsal surface of the medial column of the foot and a plantar portion shaped to conform to the medial surface of the first metatarsal of the foot and extending to the plantar surface of the dorsal surface of the first metatarsal inside part. The medial plantar portion is integrally attached to the dorsal portion. The plate has a number of perforations for receiving screws. The perforations include: a plurality of first perforations passing through the dorsal portion adapted to receive corresponding one or more first screws to be inserted into the dorsal surface of the talus of the foot; and at least one second perforation adapted to To accommodate the second perforation inserted through the plantar end of the medial plantar portion into the first metatarsal of the foot.

Description

technical field [0001] The present application relates generally to medical devices, and more particularly to implants for use in medial column arthrodesis, such as fusion of damaged, deteriorated, or fractured talus, navicular, cuneiform, and / or metatarsal bones. into the board. Background technique [0002] Arthrodesis is a surgical procedure used to artificially introduce joint osteogenesis between two bones. Arthrodesis may be performed to relieve pain in joints that cannot be managed by more conservative methods such as medications, splinting, etc. Common causes of this pain are fractures interfering with the joint, as well as arthritis. Knotodesis may be performed to fuse the tibia, talus, and calcaneus in a damaged, deteriorated, or fractured ankle region. Charcot midfoot deformity may be treated using arthrodesis, including bone resection and / or osteotomy to reduce the deformity. [0003] Arthrodesis procedures typically involve the fastening of bone plates to th...
